Adding sensors and relays to serial gateway

[sundberg84]

Hi! Do you have a gateway and a node working as a relay?

Child ID is assigned 0 for first sensor/accutor 1 for the next and so on... this is done automaticly if you use the relay sketch from http://www.mysensors.org/build/relay

for (int sensor=1, pin=RELAY_1; sensor<=NUMBER_OF_RELAYS;sensor++, pin++) {
    // Register all sensors to gw (they will be created as child devices)
    gw.present(sensor, S_LIGHT);```

Maybe if you post your code and version its easier to help you, or what you have done so far.

Thanks for the fast reply!

At this point I have my arduino nano with the mysensors serial gateway sketch uploaded to it and I have a 4 relayboard connected to the arduino. As I said, i'm new to Arduino programming and such. So the first question is, what to do next? Upload that relay code and include the code you sent?

[AWI]

@Tino Do you have only one nano for the gateway and relay node? or do you have two (a gateway nano and a node nano)?

[Tino]

@AWI

I do have one arduino nano for the gateway, which is connected to my raspberry pi with the openHAB server. And furthermore I have four arduinos that I can use as nodes to connect sensors and relays to.

@Tino Then next thing to do is get the gateway (with radio) running with the gateway sketch and verify the working with the serial monitor.

If you completed that step, build the sensor node (with radio), load the relay sketch and verify if it connects to the gateway.

@AWI

As said, I've uploaded the gateway code and received this: 0;0;3;0;14;Gateway startup complete
And I uploaded the http://www.mysensors.org/build/relay sketch to the other arduino, only changed the number of relays in the sketch. This is what I got from the relay sketch:

find parent

How to find out what the ChildIDs are of the relays? Or is this just guessing?

[Hoffan]

What are you use as controller??

[Tino]

@Hoffan I am using OpenHAB as automation on a Raspberry PI 2B and connected to a Arduino Nano.
Next to that multiple (wireless) Nano's. The Nanos are connected with a serial gateway, atleast thats whats I am trying to achieve

[sundberg84]

Find parent means the node sends a request and trying to find its way to the gateway.
Do you see anything in the gateway log during this time?

[Tino]

@AWI @Hoffan @sundberg84
I can see both sketches are working, this is what the gateway prints out:

Is this correct?
